Installation of a pipe culvert on Iowa 175 east of Morrison requires closing the roadway to traffic between Grundy County Road T-53 and Grundy County Road T-55 until late August, weather permitting, according to the Iowa Department of Transportation’s Marshalltown construction office. 

During this closure, traffic will be detoured around the work zone (see map) using Grundy County roads T-53, D-35, and T-55.
